Home Extension Builder in Yennora
A home extension in Yennora keeps the station walk — the post-war homes on standard blocks extend across the rear for the space the household needs, with the rail keeping the commute effortless.
The era read leads: the post-war fibro gets the licensed strip-out where touched, and out beats up on the lighter framing.
At the $900K to $1.15M median, the staying maths beats upsizing clearly.
We build these fixed-price, licence HBL 487805C. Ask us to measure what your block can hold.
Buildana manages the complete home extension process in Yennora — from design consultation and structural engineering through to DA or CDC approval, and fixed-price construction to handover. Extend your home without the stress.

The station walk stays
Yennora's own station is the asset extending preserves — the rear wing adds the bedrooms and living while the commute stays a walk.
The standard blocks take the family addition with the design worked to the metre.
Era handled properly
The post-war fibro gets licensed strip-out where the addition touches it, and out beats up on the lighter framing.
The strip-out is a line item up front, not a surprise.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free consultation at your Yennora home. We inspect the existing structure, check Fairfield City Council's controls, measure available space, and discuss what you need. You get a clear scope, budget range, and timeline before committing. Two design moves are usually on the table: match the existing house so the extension reads as original, or contrast with it so the new section is clearly modern. Both work — choice is aesthetic, and we'll show 3D renders of both before you commit.
⏱The Yennora construction phase. Fixed price, programmed, supervised. CDC (10–15 business days) or DA through Fairfield City Council depending on scope. Structural engineering, BASIX, and all documentation prepared and lodged. Construction Certificate obtained. Construction phase connects new to existing — footings, frame, roof tie-in, waterproofing at junction, internal fit-out and external finish. Staged works minimise disruption to your daily routine in Yennora.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection focuses on the integration: paint blend, flooring transitions, ceiling height, junction waterproofing, sound transmission. The extension shouldn't feel bolted on — it should feel like the house was always meant to be this size.
